# Check if a file exists

The `Bun.file()` function accepts a path and returns a `BunFile` instance. Use the `.exists()` method to check if a file exists at the given path.

```ts index.ts icon="https://mintcdn.com/bun-1dd33a4e-claude-bun-standalone/AcjngduDNBkyJyQv/icons/typescript.svg?fit=max&auto=format&n=AcjngduDNBkyJyQv&q=85&s=bc960f24c3d5cd52fd2d62b2b8397a15" theme={"theme":{"light":"github-light","dark":"dracula"}}
const path = "/path/to/package.json";
const file = Bun.file(path);

await file.exists(); // boolean;
```
